Answer:
4
Step-by-step explanation:
Every year, the world grows by 1.1%. Converting to a decimal, we can divide by 100 to get 1.1% = 0.011. This means that the world grows by 0.011 exponentially each year. To put this into an expression, we can add 1 to our percentage to get 1.011. This represents 1 = 100% (the original population) and the growth of 1.1% = 0.011. We multiply the rate including the growth by the population to get the population after one year. After the first year, we have
population * 1.011 as the new population after one year. We do that for every year, so the second year's population is population*(1.011)*(1.011) and so on. If x represents the amount of years, then the population can be represented as
(original population)*1.011ˣ
Therefore, to get from 7 billion to 7.31 billion, we have
7 billion * 1.011ˣ = 7.31 billion
divide both sides by 7 billion to relatively isolate the x
1.011ˣ = 7.31/7
Another way of writing this is
log (base 1.011) (7.31/7) = x
≈ 3.96
Rounding to the nearest whole number, we get 4 as our answer
Since (√36)² = (√18)²+(√18)², hence the triangle WXY is a right angle
<h3>What is Pythagoras theorem</h3>
The theorem states that the square of the hypotenuse is equal to the sum of the square of other two sides
For a triangle to be right angled, it must obey the law.
Given
Hypotenuse =√36
Other sides = √18 and √18
(√36)² = 36
(√18)²+(√18)²= 18 + 18
(√18)²+(√18)² = 36
Since (√36)² = (√18)²+(√18)², hence the triangle WXY is a right angle

Answer:
use the distributive property
Step-by-step explanation:
Use the distributive property to rewrite the expression with the GCF factored out.
<u>Example</u>:
ab +ac +ad . . . . has terms with a common factor of 'a'
When the common factor is factored out, the distributive property tells you the equivalent is ...
= a(b +c +d)
If 'a' is the greatest common factor, then b, c, d are mutually prime and no more factors can be removed to outside the parentheses.
